Soybean prices on the Chicago Mercantile Exchange have decreased due to favorable weather conditions in South America, enhancing crop prospects in Brazil and Argentina, and rising U.S.-China trade tensions, which have raised demand concerns. January soybean futures fell by 8 cents to $9.83-3/4 a bushel, while soybean meal futures increased and soybean oil futures decreased. Global export demand is shifting towards Brazilian soybeans, and the market is also affected by delays in U.S. tax credits for clean fuel production. Wheat prices saw a slight increase due to poor weather in Russia and Australia impacting crop quality, with expectations of a rise in Canada's wheat output. Overall, major crop prices have declined, with corn down 0.6%, soybeans down 0.8%, and wheat down 0.1%, as Statistics Canada is anticipated to report an increase in the country's wheat production to 35.04 million metric tons this year.
